Spring Framework FAQ: Top Questions

Spring provides i18n support using MessageSource interface and resource bundles to manage locale-specific messages.

🗺️ Steps:

1. Define messages.properties, messages_fr.properties, etc.
2. Configure ReloadableResourceBundleMessageSource.
3. Inject it and retrieve messages using getMessage().

📥 Example:

@Bean
public MessageSource messageSource() {
  ReloadableResourceBundleMessageSource ms = new ReloadableResourceBundleMessageSource();
  ms.setBasename("classpath:messages");
  ms.setDefaultEncoding("UTF-8");
  return ms;
}

🏆 Expected Output:

Returns localized messages based on the provided Locale.

🛠️ Use Cases:

• Creating multilingual web applications.
• Customizing error and validation messages.
